4To all u'lzomit may concern:

'Be it known that' I, FRAXK C. B. PAGE, a citizen o the United States,residing in the borough of Brooklvn,

county of Kings, city and State of New York. have invented certain newand useful Improvements in Punching-Machines and Feeding MechanismTherefor, cf which the following is a specification.

` and similar articles from sheets of 1in previously -rated at thepoints where the caps are to be punched r.zo

'out ofthe irregularity in the lengths o.

This invention aims to provide certain improvements in punching andsimilar machines, especially adapted to machines-which are used to punchout bottle caps deco- 'out,-and which consequently require that thefeeding Y he very accurate.

A vThe difficulty experienced with such machines arises sheets ortinAwhich are practically available, and out of the fact that the lengthsof such sheets are not commeusurable with the pattern printed thereonand tlie caps to he punched therefrom. If the printed pattern he startedregularly at one edge of the sheet, it is -:rund at the opposite edge ofthe sheet that there are a number of part;` of caps sometimesconsiderably smaller than halves. .Where the ,parts of caps are. largerthan halves or are approxi- 25 'tions .at which such small segments ofcaps would be.

punhed in the regular operation of the machine. The

desired operation may be'obtained in a variety or' ways, as, forexample, by continuing the feed regularlf.Y butr stopping the voperationofthe punch.y s during one of the feeding intervals, or by operating thepunches without interruption and giving the feeding mechanism a step 40of extra or double length at the desired point.. The timing. device fordetermining when the skip is to take place may be arranged at ang: partof the feeding and punching mechanism. Preferably the movement of thepunches is uniform and uninterrupted, and the sheet carrier is operateduniformly during the punching offthe main portion of the sheet, and witha' double interval at an ond ofthe sheet.

lAnother feature of the invention is a locking device for' holding thesheet lixedlyand accuratelyin position while the punching peration isproceeding notwithstanding any slight inaccuracy *.vh ich may bepermitted by the feeding means. The use of this lock permits a veryrapid feeding operation.

' Various other improvements are provided as hereinafter specifiedin'detail.

.trated, the sheets are fed over a tab. A

The accompanying drawings illustrate an emboutnrent oi the invention. y

Figs. Tand S are transverse sections at the same points, after apunching operationuat different periods. Figs. 9 and l() are perspectiveviews ofthe clamping device in different po- 7( =;sitio1is.

Referring to the emhodiment of the invention illusby means of a carrierconsist-ing of a pair of chains B arranged in vertical planes atopposite sides of the machine and carry'- 75 ing at suitable intervalsclamping devices designated as a whole by the letter Of The punches l'1re arranged two rows staggered relatively te 1 other, and the 'rowsare separato from each other a substantial distance as usual. Fig. 4indicates, hy the use of 89 corresponding numerals, 1, 1 2, 2, etc., thepositions relatively to each other ci the punches of the two rows. Thepunches are reciprocated as usual from a main shaft E, and the sheetcarrier is given an intermittent movement from the feeding shaft Fcarrying sprockets 35 over which the chains B run.

In order to secure the skippingmovement referred to the punches arereciprocated hy the usual connections illustrated, or by any suitableconnections, and

the feeding shaft. F is operated by means of a normal '90 pan'l G and askipping pau-l H. The former is given a movement correspondi n.1; to oneregular step or interval of tlfe feed, being' mounted upon the arm .lwhich is connected by means of a linlc K with an intermediate point of alever L which is pivoted means of a head )l provided with suitablerollers and moved by a cam X on the main shaft E. The pawl H is carriedupon one arru of a. two-armed lever O which is operated by means of alink P connected tothe outer end of the lever L. The the pawl H amovement approximately twice as great as that of the pawl G. The ratchet:.'heel Q is fixed 'upon the feeding shaft F', andis engaged by the pawlG and transmits to the shaft the regular feeding movement. A disk R,adjacent to the ratchet in the plane of the paw] H, and serves to holdthis pawl normally out of operatioil.' It is provided'vcithq notch,however, which allows `the pawl H to come into opera- `tion ateahrevolutinof the disk, and to engage the ratchet Wheel Q and givedouille-length movement. 111

wheel Q orto the shaft l", and by attaching to it a second ratchet wheelS having the diameter and the num! ber of teeth desired, and byprovidinga supplementary pawl T for giving this ratchet wheel a step ateach l5 punching operation. Upon cach complete rotation of the disk Rthe pawl ll will come into play and produce a double step. The disk ofconrseinight bef provided with two or more notches, and the ratchetwheel designed te have twice the number of teeth that there are4 regularintervals between successive skipping operations. t

leferring to Fie. 4, the preferred arrangementof the mechanism willbeunderstood. The clamping d eviees are arranged at such intervals,relatively to the standard lengths of the sheets, that the successivesheets UV have a desired distance between them, or approximately so,since the lengths commercially available vary somewhat The sheets areusually printed beforehand with a. design which is to appear upon thetop of the cap, the design being registered exactly with one edge of thesheet, which is made the rear edge when the sheet is put into thepunching machine. Such designs are indicated at \\`,in Fig. 4. Thepunchings are concentric with the design, and, supposing the feed to becontinuously regular, then the rear edge of each sheet will pass throughthe center of one of the punching-s, and one-half of a punched-out diskwill be pressed into the die. The successive positions of the punches ofthe two rows relatively to the slteets are indicated by the numerals l,2, 3, 4. 5, 6. 7 and S and i, 2 etc.

At position 4an exact half a disk will he punched out from'the rear edgeof the sheet (J. Tite dotted line represents the theoretical position ofthe forward edge of the sheet V,t.o which` however, such forward edgeseldom conforms in practite. Sometimes the edge is in advance of theline X, and sometimes in the rear of it. With the length of the sheet; Vshown. then. in position 4 there will be punched out of itsforward edgea portion smaller than one-halt' of the disk. \\`here a portion of thedisk which punched out at the edge is approximately equal to or greaterthan a half oi a disk, it is properly ejected from the die. Where it isless than half a disk, however, it is apt to become stuck in the-die.'\\'hen several such small pieces have been st ack in the die the latterno longer yields to tlze punch,

and the punch will be heut or the machine otherwisev put out of order.In order to avert this difficulty l have provided that the punchingoperation in the poA sition 4 shall be omitted or skipped. as previouslypxplained. The spacingof the sheets maybe varied from that shown,tlcntost important feature being the skipping of tlzc'openttion whichwould punch out the small portion of metal Y from tlze. edge ot' thedisk at which tle irregularity in its length isarranged tpreferahly theforward edge). The spacing,1 shown iu Fig. -t has thead- Vdldtl@ Ilsecuring all the complete punchin which "il" .be hud from theforwaidsheet lf.

'86The'lockiug may be effected in a. variety of ways. Y"Cin the machineiliustrated it is effected by means of duivels c arranged upon abracket'. f extendingfor: imdb' inno the cross-head which carries thepunches,l and Slmltd apart accurately to correspond with the intervalbetween successive feeding steps. The ciampmg devices are' provided withopenings g into which the dow-la n fit. lWhen the punches, and thecrosshead carrying them, are low-ered, s. 4c lowel c enters an OPLHHS t!of a clampingdevice carrying a sheet, and 96 thus hulde tlmplampingdevicc and the sheety rigidly in. PUSUH regardless of the wearoi the chain or any inaccuracy in the feeding mechanism. In fact thielocklng device permits of a. perfect operation of the mal, chine with amuch less accurate feeding mechanism 100 than has been previouslypermissible. The foremost U lllt dmtvls c is so far in advance of thepunches as to. lock thc clamping devices and a sheet held between htm lor before the time that the forward edge of the Sllcct chicks thepunching position. At the nextstep U10 StWlhl duwt-1 c comes into play,and so on to the last punching operation.

A fixedmember or base carries the lower jaw i, hich is extended forwardly andrearwardly beyond the body of the device to provide a rest for the sideedge of the sheet. and which carries stops j for limiting the positionof the sheets laterally. The fixed member also includes a pair of lugs karranged to fit in the'trougly` Slmpttl :luide d, and to carry one ofthe pins of the Chili liv The fixed member carries also :t central p0r-125 lim 7'1 Ptvjccting upward slightly` and. in which is ftllmtl theopening y. preferably with a renewable bllllh: thor/).

Crank arms a 130 arepivoted at r upon oppositiel sides of the centml Efixed portion n1, andhave' their free ends connected by means of links s with the lower endsof the downward arms o. -The arm q` and link z thus form a toggle, thearms q being provided with stops t. limiting the upwird movement of thelinks s. A spring u tends to hold the device opened or closed occordin;:is it is swung downward or upward pa st the center r.

At the forward end of the table is arranged a stop 'v (Fie. 3) againstwhichrthe rear edge of each new plate is set, this stop being anadjustable gage to register I the printed sheet with the punches. Whilethe sheet stands in thisposition the clamping devices C come to theirproper position for engagement with the sheet, and are clamped upon itsedges near its rear end, and carry it forward. For closing the device inthis position a topper u (FigA` 1) is provided which moves up and downwith the movement of the crosshead carry# ing the punches, and, strikingvthe under side of the wear plate carried ou the rodconnecting the crankarms q of the device, lifts the ends oitheso crank arms to'the clampingposition of Fig. i0.. After the sheet has been completely` punched it isreleased from the clamping action of the devices: by means of a swingingtappet y (Figs. 2 und 3) striking downward upon the plate :c of thedevice.

The tappets 'w are carried upon .slides i h ving a 'rack and pinionengagement with sectors 1G carried on short shaits 10 carried inbearings l0'l and 103 and which are oscillnted by means of links 1lconnected to the cross-head extension. The tsippets y 'are carried uponarms of short shafts 1?.- mounted in fixed bearings upon the frame, andoscillated [rom the oscillfiting shaft 13 running below the dies (undusu` :illy operating the ejectorsl.

Themeans for removing the finished caps is' illustrated best in Figs. 6,7 :in-d8.A A sweeper l lies immediately obove the fixedplnte 15 (whichmay be supported from the plates h'as shown) and reciprocales fromthwposition shown in dotted lines to thht shown in full lines. tfxcntlte'pluugers'are down the sweeper lies in the dottui vlineposition. Asthe plungers nre raised the-ejectors 16 lrelso raised to the level` ofthe plate 15. 1`hereupon.the sweeper 14 .moves forward and sweeps thecaps 17 off the ends of the ejeclors and to the edge.. of the fixedplate 15, where they fall off into a 'hopper 18 and re gathered in areceptacle 19 below. The sheet in certain positions extends over themouth of the hopper 1S, but the caps are considerably smaller than theopenings in the sheets'(being drawn as well as punched), and with theconstant. vibmtionof the machine all the cops drop readily through theopenings in the sheet. The end of the' sheet is supported upon theguides 2 0, and when it has been entirely punched and released 'from theclamping nuts itelides oft' into any suitable receptacle arranged toreceive the scrap.

Any suitable' means may be provided for operating7 the sweeper, such,.for example,` ns the slides 2l uttached to the opposite bent-.up endsthereof and rc- Aciprocsted in fixed guides 22 by mcansoflinkconnections to the. contantly-oscill-.tting inner :mn 2 3 n n Shaft23 having an' outer arm 222-', which is operated in turn by a link 24connected to u lever 25 operated i by a link 26 pivoted thereto undreciprocutcd by cams 65 27 28 (Fig. l) on the overhead shaft i Themachine may also bc made to operate without the.cutting of anyfractionhl pieces, by the use ok sheets which meesure with substantialcxnctness to the standard length. For example, lthe sheets may besheared to lengths commensurate. with the size ot the punchings, andarranged iro that their forward edges will coincide substantially withthe liuc X, Fig. 4; and with such sheets the operation of the punches inthe positifons 4, 4. would be skipped.

Though l have described with great particularity oi detail certainembodiments of my invention, yet it is not to be understood therefromthat the invention is limited to the particular embodiments disclosed.Various modifications thereof in detail and-in the ar- 30 rangement andcombination of the parts may be made by those skilled in the art.without departure irom the invention. i
